拷贝文件和目录是每一个操作系统的基本指令。备份行为基本上是创建文件和目录的副本。在Linux系统下,我们可以用cp命令来实现。
正如我们在上文提到的,cp是一个用来创建文件和目录副本的命令。在这里我们提供了一些在日常操作中可能用到的cp命令的实例。 继续阅读Linux cp 命令的15个示例 – 创建文件和目录的副本

OAuth是一个关于授权(authorization)的开放网络标准,在全世界得到广泛应用,目前的版本是2.0版。
本文对OAuth 2.0的设计思路和运行流程,做一个简明通俗的解释,主要参考材料为RFC 6749。
为了理解OAuth的适用场合,让我举一个假设的例子。
有一个”云冲印”的网站,可以将用户储存在Google的照片,冲印出来。用户为了使用该服务,必须让”云冲印”读取自己储存在Google上的照片。
问题是只有得到用户的授权,Google才会同意”云冲印”读取这些照片。那么,”云冲印”怎样获得用户的授权呢?
传统方法是,用户将自己的Google用户名和密码,告诉”云冲印”,后者就可以读取用户的照片了。这样的做法有以下几个严重的缺点。
(1)”云冲印”为了后续的服务,会保存用户的密码,这样很不安全。
(2)Google不得不部署密码登录,而我们知道,单纯的密码登录并不安全。
(3)”云冲印”拥有了获取用户储存在Google所有资料的权力,用户没法限制”云冲印”获得授权的范围和有效期。
(4)用户只有修改密码,才能收回赋予”云冲印”的权力。但是这样做,会使得其他所有获得用户授权的第三方应用程序全部失效。
(5)只要有一个第三方应用程序被破解,就会导致用户密码泄漏,以及所有被密码保护的数据泄漏。
OAuth就是为了解决上面这些问题而诞生的。
1、连接mysql服务器
mysql -u root -p -S /mnt/data/mysql/mysql.sock
2、创建用户
insert into mysql.user(Host,User,Password) values (‘%’, ‘test’, password(‘test123′));
3、创建数据库
create database testdb
4、设置权限
grant all privileges on testdb.* to testdb@’%’ identified by ‘123’;
5、刷新权限
